01 / Roof replacement
When repairs stop making sense, replacing the roof is the right way to protect the house. A new roof in Los Angeles has to handle strong sun, a few very heavy storms, Santa Ana winds and, in hillside neighborhoods, fire-rating rules. Denali Builders CA replaces shingle, tile and flat roofs across Los Angeles, handles the permit, and stays through the final city inspection.
02 / When to replace
When roof replacement makes sense
There is no single sign that tells every homeowner it is time. The age of the roof, how much of it is damaged, how often it has needed repairs and the condition of the material all matter. A roof can sometimes keep performing well when it is old, while another needs replacing sooner because of damage or poor installation.
An aging roof
Every roofing material wears out, and how fast depends on the material, the quality of the original installation, maintenance and sun exposure. An inspection shows how much useful life is left, especially if an older roof has started to leak or shed granules.
Repairs that keep coming back
Occasional repairs are normal. Repairs in several places, or the same leak returning, suggest the roofing system is failing as a whole. At some point it costs more to keep patching than to replace. See roof repair for what a repair can and cannot do.
Widespread shingle or tile damage
A few damaged shingles or tiles can be replaced one by one. When damage is spread across the roof, or moisture has reached the layers underneath, a full replacement is more reliable.
Leaks and water stains
A single leak does not automatically mean a new roof. Several leaks, or damp decking found when a repair is opened up, usually do.
03 / Materials
Roofing materials for Los Angeles homes
Asphalt shingles
The most common choice on Los Angeles houses. Architectural shingles come in many colors and suit most home styles. Look for a Class A fire rating and, where the city requires it, a cool roof rating. See asphalt shingle roofing.
Clay and concrete tile
Tile fits Spanish, Mediterranean and many other Los Angeles home styles and lasts a long time. It is heavy, so the structure has to be checked before changing materials, and the underlayment beneath it is usually what needs replacing first. See tile roof repair and replacement.
Flat and low-slope systems
Garages, additions and many mid-century homes have roofs with very little slope. These use membranes such as TPO or modified bitumen rather than shingles or tile. See flat roof repair and installation.
Metal, slate and rubber
We also work with metal, slate and rubber roofing where they suit the house. Slate and tile are heavy, and whichever material you choose, the roof structure and local fire and energy rules decide what is practical.
04 / The process
What happens during a roof replacement
Inspection and estimate. We look at the roof and attic, explain the condition and give you a written estimate with the material options.
Permit. We pull the permit with the city that covers your address.
Tear-off. The old roofing is removed so the roof deck underneath can be seen, not covered over.
Deck repair. Soft or damaged decking is repaired or replaced, because new roofing is only as sound as what it sits on.
Underlayment, flashing and new roof. We install new underlayment, flashing and drip edge, then the new shingle, tile or flat roof system.
Clean-up and final inspection. The crew cleans up each day, and we schedule the final city inspection.
05 / Permits and code
Permits, fire rating and cool roof rules in Los Angeles
In the City of Los Angeles the Department of Building and Safety (LADBS) issues roofing permits and inspects the work. A few rules shape what you can install:
- Permit and inspection. Replacing a roof covering needs a permit and a final inspection.
- The half-roof rule. If more than half of the roof is replaced within a year, the entire roof must meet current code. If half or less, only the replaced area must.
- Fire rating. In Very High Fire Hazard Severity Zones, which cover many hillside areas, the roof covering must be rated Class A. Wood shakes and shingles cannot be used for re-roofing in the city.
- Cool roofs. California's Energy Code (Title 24) requires cool roof products, rated by the Cool Roof Rating Council, on many replacements. The minimums are stricter for low-slope roofs than for steep ones.
Neighboring cities have their own building departments. See areas we serve for who issues the permit where.
06 / Cost
What affects the cost of a new roof
A fair estimate depends on the job, not on a rule of thumb. These are the things that change the number:
- Roof size, slope and complexity: valleys, dormers, skylights and chimneys all add detail work
- The material you choose
- How many layers have to come off
- Deck repairs found after tear-off
- Access to the property and where materials and debris can go
- Extras done at the same time, such as gutters, attic insulation or solar panel removal and reinstall
07 / Choosing a roofer
Choosing a roofing contractor in Los Angeles
- Check the license on the Contractors State License Board website and ask for proof of insurance.
- Get the scope, materials and schedule in writing, including who pulls the permit.
- Ask what happens if rotten decking is found after tear-off.
- Ask how the crew protects the house and landscaping, and how it handles rain.
- Compare estimates line by line, not by the bottom number alone.
08 / Aftercare
After the new roof
A new roof still needs a little attention. Look it over after big storms, keep gutters and valleys clear, trim branches that hang over it and keep foot traffic off tile. A periodic roof inspection catches small problems early.
09 / Why Denali
Why Denali Builders CA
Denali Builders CA is a licensed and insured roofing contractor in Los Angeles with 150 Google reviews averaging 4.9. Many customers describe the same things: an honest estimate, a crew that cleans up daily, and a job that ends when it was supposed to. More on the reviews page.
We hired Denali Builders to rip off and re-roof our home in Los Angeles (prior to a solar install). [...] The city inspector said our roof job is one of the best he's ever seen.
Denali worked hard in adverse circumstances to get the project (a complete reroof) completed on time and with an eye on quality.
How do I know if I need a roof replacement?
An aging roof, leaks in more than one place, widespread curling, cracking or granule loss on shingles, and repairs that keep coming back all point toward replacement. None of these decides it alone. An inspection tells you the actual condition of the roof and whether repair would still make sense.
Can I replace only the damaged part of my roof?
Often yes, when the damage is isolated and the rest of the roof is in good condition. In the City of Los Angeles, replacing more than half of a roof within one year brings the whole roof up to current code, so a large partial replacement can end up costing nearly as much as a full one.
What does a roof replacement cost in Los Angeles?
It varies from roof to roof. Size, material, slope and complexity, the number of layers to remove, deck repairs, access and extras such as gutters or skylights all change the total. We do not guess a price from the street. We look at the roof and give you a written estimate for the actual job.
How long does a roof replacement take?
It depends on the size and design of the roof, the material and the weather. A smaller, simple roof goes faster than a large or complex one, and deck repairs found after tear-off can add time. We explain the expected schedule before work begins.
Do you handle the permit?
Yes. We take care of the permit and schedule the final city inspection, so you do not have to deal with the building department yourself. Our customers mention this often in their reviews.
Can you remove and reinstall solar panels?
If you have solar panels, the roof and the panels are best planned together because panels often have to come off and go back on. Some customers have re-roofed before a solar installation. See our solar system page.
